It's true that LISTSERV needs dedicated port 25 access to one IP address 
on the server.  If you can configure an outbound SMTP server to run on a 
non-standard port or on a single IP on the server, you can run it on the 
same server as LISTSERV.  (Alternately, you could configure LISTSERV to 
listen on a non-standard port, assuming your SMTP server knows how to 
route SMTP mail to that port.)  The documentation is correct in the 
simplest (most common) case, but there are work-arounds for most 
products.

As an example, see the L-Soft whitepaper on configuring LISTSERV and IIS 
SMTP to run on the same server:

http://www.lsoft.com/resources/wp-iis-smtp.pdf

We've also been successful in setting up LISTSERV to co-exist with 
Exchange server by adding a second internal IP address to the server and 
binding Exchange to the external IP and LISTSERV to the internal one, and 
then configuring an Exchange connector to route mail to the internal 
LISTSERV IP via a dedicated FQDN.  A bit more complicated, but possible. 
You could do the same in principle for any SMTP server that can be 
configured to listen on a single IP address and can route mail to a 
specific IP based on its FQDN.  (This of course requires separate FQDNs 
for LISTSERV and the Exchange server, although they may point to the same 
external IP address.)
